I don't know what the deal is, I edited the core lights to be dim.... set them at 0.5, but they went back to defaults when I loaded the map in-game. I went back and opened the editor and sure enough it was as if I never changed them.

I did 2 full builds after changing it 2 more times and cooking, but it always goes back to the default in-game and when I load it back up in the editor. Can this not be changed?

I wouldn't care so much if the light didn't go through the walls... and the setting I tried to block that aren't working either...
